Balance the Moisture in Your Home
Humidity affects everything from how comfortable your home feels to how well your HVAC system performs. In our region, summers bring high humidity that can feed mold growth, cause musty odors, and make your home feel warmer than the thermostat reads. Winters bring dry air that cracks hardwood floors, peels paint, causes static electricity, and irritates your skin, sinuses, and respiratory system.
Girdner Heat and Air installs and services whole-home humidifiers and dehumidifiers that integrate directly with your HVAC system to maintain healthy moisture levels throughout your home automatically. According to the EPA, indoor relative humidity should be kept between 30-50% to minimize mold growth and maintain comfort. A whole-home system maintains that range year-round without the hassle of filling, emptying, or moving portable units from room to room.
Humidity Control Options We Install
We help homeowners choose the right system based on whether moisture is too high, too low, or both at different times of year. We install and service:
- Whole-house humidifiers that add moisture during dry winter months
- Whole-house dehumidifiers that remove excess moisture in summer
- Bypass humidifiers that work with your furnace and existing ductwork
- Steam humidifiers for precise humidity control in larger homes
- Crawl space and basement dehumidifiers for moisture-prone areas
Each system integrates with your existing HVAC equipment and is controlled by a humidistat that monitors moisture levels and adjusts output automatically. We assess your home’s humidity patterns before recommending a system so you get the right solution for your specific situation. For homes that deal with both dry winters and humid summers, we can install both a humidifier and a dehumidifier so your indoor moisture stays balanced all year.
Professional Humidity System Installation
A whole-home humidifier or dehumidifier needs to be properly sized, positioned, and connected to your HVAC system to work correctly. Our technicians install humidifiers directly onto your furnace or ductwork and connect them to your home’s water supply for hands-free operation. Dehumidifiers are installed in-line with your duct system or as standalone units in basements and crawl spaces with proper drainage.
Every installation includes system calibration, humidistat setup, and a walkthrough of how the system operates. We also explain the maintenance schedule, including filter or pad replacement for humidifiers and drain line checks for dehumidifiers. Proper maintenance keeps your system performing efficiently and prevents issues like mineral buildup or standing water.
We serve both residential and commercial properties. Businesses that require specific humidity levels, such as medical offices, server rooms, and storage facilities, can benefit from commercial-grade humidity control systems sized for larger spaces and more demanding requirements.

Had a great experience, especially the consultation! The information was as they presented, no hidden extras, it was a successful home project and the boys were so great to talk to and ask questions. All were knowledgeable and all worked efficiently. They also seemed to enjoy their work and how they happily carried one with each other. They needed to take more of the snacks but they were such a great representative of Girdners to have on our home projects! Highly recommended. Owner is also great to work with. Looking forward to working with the company again!!

We had our HVAC system replaced in August 2024, and the experience was excellent from start to finish. The team completed the installation in a very timely manner and has been a pleasure to work with ever since. The system has worked perfectly, and anytime we’ve had a question, they’ve responded quickly and professionally. We are very, very happy with both the product and the service—highly recommend!

FAQs About
Humidifiers and Dehumidifiers
How do I know if I need a humidifier or a dehumidifier?
If your home has dry, scratchy air in winter, static electricity, cracked wood, or frequent nosebleeds, you likely need a humidifier. If you notice condensation on windows, musty smells, visible mold, or your home feels clammy in summer, a dehumidifier is the solution. Many homes in our region benefit from both since humidity levels swing significantly between seasons.
Is a whole-home system better than a portable unit?
For most homeowners, yes. A portable humidifier or dehumidifier only treats one room and requires manual filling or emptying. A whole-home system integrates with your HVAC equipment, treats every room, adjusts automatically through a humidistat, and requires far less maintenance. The comfort difference is noticeable throughout the entire house.
Can excess humidity damage my home?
Yes. Humidity above 50% promotes mold and mildew growth, can cause wood rot in structural framing, damages drywall, and creates conditions for dust mites to thrive. In basements and crawl spaces, uncontrolled moisture can lead to serious structural problems over time. A whole-home dehumidifier keeps levels in the safe range year-round.
How much maintenance does a whole-home humidifier need?
Most whole-home humidifiers require a water panel or evaporator pad replacement once per heating season. We also recommend an annual inspection to check for mineral buildup, verify water supply connections, and clean the unit. Our maintenance plan covers these checks as part of your regular HVAC tune-up.
Can you install a dehumidifier in my basement or crawl space?
Yes. We install standalone dehumidifiers designed specifically for below-grade spaces. These units handle the higher moisture loads typical of basements and crawl spaces and include drainage connections so you never have to empty a collection bucket. Proper basement humidity control also improves the air quality throughout your entire home.
